如何根据一个csv文件替换另一个文件csv的值？

import csv

def replace_csv_values(source_csv_path, target_csv_path):
    with open(source_csv_path, 'r') as source_file:
        source_reader = csv.reader(source_file)
        source_data = list(source_reader)
        
    with open(target_csv_path, 'r') as target_file:
        target_reader = csv.reader(target_file)
        target_data = list(target_reader)
        
    for source_row in source_data:
        # 获取需要替换的值和对应的行号，假设第一列是唯一标识符
        replace_value = source_row[1]
        replace_row = int(source_row[0])
        
        # 替换目标CSV文件中的对应行的值
        target_data[replace_row][1] = replace_value
    
    with open(target_csv_path, 'w', newline='') as target_file:
        target_writer = csv.writer(target_file)
        target_writer.writerows(target_data)
